Passage Two.docx ( 880 lexile ) WASHINGTON, D.C. A survey has found that almost half of all Americans are avoiding social networking Web sites such as Facebook, MySpace, and Twitter. People are growing weary of being in constant communication. Some are even beginning to avoid Internet technology altogether. The survey found that even some young adults, who helped drive the rapid growth of such sites, say they would enjoy a break from the sites. They are not stopping completely, however, for fear they will miss out on something. The Pew Internet & American Life Project conducted the survey. It found that 48 percent of Americans of all ages are indifferent about communicating through social networking Web sites. In addition, many feel overloaded by gadgets , or have begun avoiding Internet use altogether. Eily Toyama, 32, can relate to this so-called "Facebook fatigue." Toyama recently created a Facebook page. This was only after giving in to peer pressure, however. She rolls her eyes at the thought of establishing a Twitter account. "I just don't think people need to know that much about my life," Toyama said. She was referring to Twitter. Its main purpose is to keep friends and family updated on all of the Twitterer's activities. Mike Nourie is a 20-year-old college student in Boston, Massachusetts. He admits to feeling burdened by the overabundance of communication gadgets available today. Nourie spends his summers working at an inn on Cape Cod. Wireless Internet service is spotty there. Escaping social networking for the summer, he said, is a huge relief. "It gives me a chance to relax and [concentrate] on other things like music, work, and friends," Nourie said. Alex Slater, 31, has taken an even bigger step away from social networking. Slater has shut down his Twitter account. He has also stripped information from his Facebook page. Slater explained that it feels inappropriate to be exposed to details ranging from "someone's painful breakup to what they had for breakfast." According to Pew researchers, 7 percent of those surveyed said they do not go anywhere without their mobile communication devices. Still, this group of young people feels conflicted about staying in constant contact. Pew researchers called this group " ambivalent networkers." "They have this anxiety about shutting off," said John Horrigan. Horrigan is a manager at Pew."They're afraid they might be missing something," he said. "But we also find them [longing] for a break." Gary Rudman is a market researcher. Rudman has also observed indications that young people are suffering from communication overload. "Who wouldn't be fatigued?" Rudman said. "With Facebook, LinkedIn, Plaxo, and Twitter, young adults struggle to keep up to avoid [being left out of the loop]." Experts say this is not surprising. Many say that humans want social exchanges, both online and off. However, research shows that people recognize the differences in the quality of these exchanges. Communication by way of social networking Web sites often comes in short bursts. This frequently leaves people thirsting for more meaningful conversation with others. Craig Kinsley is a professor at the University of Richmond. "Many short contacts may leave the user wanting deeper, more meaningful exchanges," said Kinsley. "A good conversation with a good friend is [worth more than a few short] or emoticon -filled lines in a [text message]." The Associated Press contributed to this story.
